The building and stairs are non-combustible. If the stairs are not heated can it be considered outside the building envelope?
Which leads to a side observation. We provide sprinklers for balconies and below combustible overhangs that are over 4 feet wide. And won't that be outside the building envelope? So would not sprinklering outside the building envelope be a valid argument?
